Yes it is, my RAM is PC3200 (much slower than yours but nothing the cas latency can't catch up on) and mine runs at about 35MHz faster than yours, I don't know why this is but it is definitely running slow.
do u think if i change the memory from GeIL 1GB (2x512MB) PC5300 667MHz Value DDR2 Dual Channel Kit to Corsair 1GB DDR2 XMS2-5400 TwinX (2x512MB) you think it will be the normal speed?
im not sure it is going slow yet, thats the page with the specs of the memory but not its current speed, could u plz post an image of the "motherboard" page
